inheritance class python code example

Example 1: python inheritance

class Person:  
    name = ""  

    def __init__(self, personName):  
        self.name = personName  
  
    def showName(self):  
        print(self.name)  
  
class Student(Person): 				# Student inherits from Person superclass
    studentClass = ""  

    def __init__(self, studentName, studentClass):  
        Person.__init__(self, studentName)		# superclass constructor
        self.studentClass = studentClass  		# Student class specific
  
    def getStudentClass(self):  
        return self.studentClass  
  
  
person1 = Person("Dave")
person1.showName()                  # Dave
student1 = Student("Mary", "Maths")
print(student1.getStudentClass())   # Maths
student1.showName()                 # Mary

Example 2: Inheritance example python

class Parent:

    def abc(self):
        print("Parent")

class LeftChild(Parent):

    def pqr(self):
        print("Left Child")

class RightChild(Parent):

    def stu(self):
        print("Right Child")

class GrandChild(LeftChild,RightChild):

    def xyz(self):
        print("Grand Child")

obj1 = LeftChild()
obj2 = RightChild()
obj3 = GrandChild()
obj1.abc()
obj2.abc()
obj3.abc()

Example 3: inheritance in python 3 example

class Robot:
    
    def __init__(self, name):
        self.name = name
        
    def say_hi(self):
        print("Hi, I am " + self.name)
        
class PhysicianRobot(Robot):
    pass

x = Robot("Marvin")
y = PhysicianRobot("James")

print(x, type(x))
print(y, type(y))

y.say_hi()

Example 4: inheritance in python 3 example

<__main__.Robot object at 0x7fd0080b3ba8> <class '__main__.Robot'>
<__main__.PhysicianRobot object at 0x7fd0080b3b70> <class '__main__.PhysicianRobot'>
Hi, I am James

Example 5: how to inherit a class in python

class Sparrow(Bird):
        def sound(self):
                print ("ChiChi!")
 
birdobj = Sparrow()
birdobj.eat()
birdobj.sound()
